Currently the status for the SimpliSafe sensors does not import for door, window, motion, etc. The attributes you are seeing are mapped to the system itself and any alarms the system may report (fire, water, burglary).
The presence is mapped to if the alarm is set to away. Not present = Away, present = Off/Home
Active / inactive maps to if the alarm is armed or not. Active = armed, inactive = not armed
Open / closed maps to an active alarm. Open = burglary alarm, closed = no alarm
You can interact with SimpliSafe through RM by using custom commands, such as Off/Home/Away
And trigger actions based off the mapped events
